Check chain sharpness
A sharp chain makes wood chips. A dull chain makes
a sawdust powder and cuts slowly. See CHAIN
SHARPENING.
Chain sharpening
To sharpen cutting teeth you will need a round file
and a file gauge. See instructions under the heading
Technical data for information on the size of file and
gauge that are recommended for the chain fitted to
your chain saw.
Always file cutting teeth from the inside face. Reduce
the pressure on the return stroke. File all the teeth on
one side first, then turn the chain saw and file the teeth
on the other side.
File all the teeth to the same length. When the length
of the cutting teeth is reduced to 5/32 inch (4 mm) the
chain is worn out and should be replaced.
When you sharpen the cutting tooth (A) the depth
gauge setting (C) will decrease. To maintain optimal
cutting performance the depth gauge (B) has to be
filed down to achieve the recommended depth gauge
setting. See instructions under the heading Technical
data to find the correct depth gauge setting for your
particular chain.
a WARNING! The risk of kickback is increased
if the depth gauge setting is too large!
The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. We recommend
